See my post earlier in this thread above repeated here:
Yes, you are right we need both types of fiber but we need to be very careful with insoluble fiber and keep it down to small amounts. You are also right that each one of us is different and can tolerate more or less of the IF.
The point here is that if you suggest a high IF product such as barley grass powder, you should accompany it with the caveats you are suggesting now. Otherwise newbies (or others) might use the product and not be aware of the need to be careful.
Cheers.

I use 20 cc (about 1.35 tablespoons) of psyllium husk with each meal. It is 70% SF and 30% IF. I keep my other sources of IF low. Is psyllium husk a good source of IF? Why is psyllium husk not reccomended on this website?
Cheers.

Psyllium husk is an excellent source of both IF and SF. I used it regularly for many years. It is the soluble fiber supplement most tested in clinical trials and frequently recommended by doctors. In 2007 the British Gastroenterology Society and recently the US College of Gastroenterologists released guidelines for the practical treatment of IBS. Both organizations reported that psyllium is moderately effective for managing IBS.
I also recalled reading on the website that psyllium made symptoms worse which was contrary to my experience. While researching the topic I came across a discrepancy between an abstract report in the research library and the actual abstract of the original article published in the prestigous GI research journal GUT.
The original article concluded "Conclusions: Consumption of a high fibre diet retards intestinal gas transit by decreasing bolus propulsion to the rectum. Thus, in addition to increasing gas production by colonic flora, fibre ingestion may elicit gaseous symptoms by promoting gas retention."
The conclusion mistakenly reported in the library was "Conclusions: Consumption of a high psyllium fibre diet retards intestinal gas transit by decreasing bolus propulsion to the rectum. Thus, in addition to increasing gas production by colonic flora, psyllium fibre ingestion may elicit gaseous symptoms by promoting gas retention."
The word "fibre" was replaced with the words "psyllium fibre" throughout the reported abstract. This mistake leads to the questionable conclusion that psyllium is responsible for increase gas retention when in fact the research actually reported that fiber maybe responsible for increase gas retention. I reported this error to Heather in March of last year.
This small study on 10 healthy subjects artificially injected mixtures of gases through a tube into jejunum and collected the expelled gas. The authors acknowledge that it is unclear whether pysllium or other fiber supplements affect the transit of naturally produced GI gases in the same manner. Also, the psyllium was taken with normal meals that contained other dietary fibers. The effects of the psyllium could have been confounded by dietary fibers in the meals.
Perhaps the misreported abstract partially contributed to some of the negative comments about psyllium fiber increasing intestinal gas in some IBSers.

Thank you for your insightful response and your fine detective work in discovering this error.

whenever we mention any IF food we should say, as I do, that it is eaten with or after SF. When I recommend oranges, for instance, I say eat them after a banana or mango.
However, it is impossible to not confuse some of the people some of the time. believe me!

if it works for you, great, that's what counts. I don't recommend it as a fiber supplement for IBS because it's not 100% soluble fiber. And I've heard from too many people about the bloating/gas issue.
But again, if it doesn't bother you, then that's all that matters.

Psyllium husk is certainly no magic bullet. On the other hand, I have not found anything that is. It has its advantages and disadvantages like anything else.
I have been using it for a long time - it provides me with a source of both SF and IF. It seems to provide more girth to my stools than otherwise.
It is my main source of IF.
I do get bloating and gas, some days a little and some days a lot and some of it may come from the psyllium.
Since we do need both SF and IF in our diet, it seems to me to be a reasonable strategy to get them both from the same source.
Cheers.

A big reason we need SF and IF is for the nutrition in those foods. IF foods especially have a lot of needed nutrients. If you get so much fiber from a fiber supplement it shouldn't take the place of real fruits and vegetables. There is nothing wrong with the idea of ingesting IF and SF together; that is a good plan. But it is better to eat IF than supplement with it.
